Abstract: Provided is a method, system, program, and computer readable medium for maintaining a database of objects. At least one structured document is received representing an instance of an object including attributes and attribute values defined for a class. Content of the structured document representing the object is added into the database, wherein the database is capable of storing multiple structured documents representing multiple objects. In another implementation, an instance of at least one object including attributes and attribute values defined for a class is generated. For each generated object, a structured document is generated representing the object and including a representation of the attributes and attribute values in the object. Each structured document is transferred to the database to maintain.

Abstract: Provided is a method, system, and program for maintaining a database of data objects. A first data object implemented in a first programming language including attributes and attribute values for a class is received. The first data object is transformed to a second data object implemented in a second programming language, wherein the second data object includes the attributes and attribute values of the class included in the first data object. The second data object is added to the database, wherein the database is capable of storing multiple data objects implemented in the second programming language.

Abstract: Provided are a method, system, data structures and article of manufacture for implementing an array of persistent elements. A class of the array of persistent elements has a constructor. A call is received from an application executing in a runtime environment to the constructor. The constructor is processed to create an empty array of persistent elements. A persistent element is included into the array of persistent elements within the runtime environment by storing persistent data of the added persistent element in a data record and the address of the data record at a corresponding index record.

Abstract: Provided is a method, system, program, and data structures for indexing object oriented objects in an object oriented database. An object data structure is provided including a plurality of object oriented objects, wherein each object includes a key value, and wherein each object is associated with an object index. A node data structure is provided including nodes, wherein each node represents one object in the object store and includes one object index used to access the object represented by the node in the object store. The nodes in the node data structure are organized according to the key values in the objects represented by the nodes. The node data structure is used to access the objects in the object store.
